FRED 3. KING, OF 'IQLEDO, OHIO, ASSIGNOR TO THE WILLYS- OVERLAND COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

SPRING-SEAT STRUU'IURE.

To all whom it magi concern."

Be it known that I, FRED B. KING, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Spring-Seat Structures, ofwhich I declare the following to be a. full, clear, and exact description.

This invention relates to improvements in spring seat structures, particularly with reference to the base portion thereof. While it is designed for use primarily in automobiles, the invention finds ready application generally in the art of upholstery, as for example, in chairs, lounges, beds, etc.

One object of the invention is the provision of a seat base which shall be very strong and at the same time economical for manufacture in large quantities because of the labor saved in assembling the seat in which it is embodied.

Another object is the provision of a seat base which embodies in itself all of the fastenings necessary for attaching other parts of the seat thereto.

Objects relating to economies of manufacture and details of construction, and other objects, will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the present application, I have illustrated in the accompanying drawings, in which:

Figure I is a plan view of a seat base embody ng my invention with the springs in place thereon,

F II is a fragmental view on a larger scalejpf a Fig.

III is a vertical section taken on the line "IjII -III of Figs. I and II.

F IV is a perspective, detail view showing lie means for connecting the base with portion of the structure shown in the springs and with the cushion apron.

Like reference characters refer to similar parts throughout the views.

In the drawings, 10 represents the seat cushion from which depends an apron 11 of upholstery material. The lower'edge of the apron is preferably beaded, this being accomplished by folding the edge over a cord or thelike 12, and stitching along the line indicated at 13' in Fig. IV. This is The cushion 10 rests' common practice. upon a series of helical sprin 14, preferably of the hour glass type, t e tops of the springs being fastened together in any approved manner.

At the bottom, the springs rest upon and are secured to a base 15 which consists of a stamping of sheet metal in which are formed downwardly extending bosses or corrugations leaving grooves on the upper side of the stamping. These bosses or corrugations serve to stiffen the base. Their particular form and arrangement are immaterial. As shown in the drawings, I have employed bosses forming on the upper side of the base circular grooves 16 and 17, an inner rectangular groove 18, and an outer rectangular groove 19 into which merge a plurality of longitudinal grooves 20. At the center of the base there maybe provided a breather opening 21 through which air is free to pass into and out of the seat structure.

At proper positions throughout the base 15, fingers 22 are struck up out of the metal of the base and when the springs 14 are in proper position, these fingers are bent down over the lower coils of the springs to securely fasten the same to the base.

Along the periphery of the base, a relatively deep groove 23 is formed, the outer wall thereof extending preferably slightly above the main or flat portion of the base.

This groove receives the bead at the lower edge of the apron 11. Fingers 24 are struck up out of the base adjacent to this groove, and when the apron head is in place therein, the fingers may 'be bent downwardly and outwardly over the bead, there y clamping it securely to the base.

In-assembling the seat, each spring14 is placed upon the base; with its lower coil enclosing'two of the fingers 22 and the latter are then bent down as previously stated. After all of the springs are mounted in their proper places upon the base, the workman fastens their upper ends together by any of the well known means adapted to permit limited relative motion only. Thereafter the cushion 10 with the apron 11 sewed thereto is laid upon the springs and the whole seat is inverted when pressure may be applied to compress the springs 14 sufiiciently to enable the workman to draw the beaded edge of the apron into the groove 23 readily. The head is' then clamped in place in the groove by the fingers 24 which into p0sition, as shown in the drawings, by

are pressed means of a tool having one jaw small enough to pass through the holes in the base left by the striking up of the fingers 24.

While the form of structure herein shown and described is admirably adapted to fulfill the objects primarily, it is to be understood that various changes in form, proportions and minor details of construction may be resorted to, within the scope of the appended claims, and that I do not wish to limit myself to the specific design and construction shown and described except inasfar as I have included said limitations within the terms of the following claims, in which it is my intention to claim all novelty inherent in my invention broadly as well as specifically.

What I claim as new and desire to secure by Letters Patent, is:

1. In a seat structure, a cushion provided with an apron, springs for supporting the cushion, a base formed of a single sheet of metal for supporting said springs, means integral with'the base for securing the lower ends of the springs thereto at substantially opposite points, and means integral with cushion, a base formed of a single sheet ofiii the base for securing the lower edge of the apron thereto.

2. In a seat structure, a cushion provided with an apron, springs for supporting the metal grooved along its edge to receive the lower edge. oi the apron, fingers struck up from the base adjacent to said groove and adapted to clamp the apron within the groove, and fingers struck up from the base for securing the lower ends of the springs thereto.

3. In a seat structure, a cushion provided with an apron, springs for supporting the cushion, a flat sheet metal base, late, grooved along its edge to receive the ower edge of the apron, means integral with said base plate and adjacent said groove for gripping the lower edge of the apron in said groove, and means integral with said base plate for securing the lower ends of the .springs thereto.

4 In a seat structupe, a cushion provided with an apron, springs for supporting the cushion, a sheet metal base plate grooved along its edge to receive the lower edge of the apron, means integral with said base plate for gripping the lower edge of the apron in said groove, and fingers struck up from said base plate and bent over the end coils of said springs on opposite sides thereof for securing the same to. the base plate.

5. In a seat structure, a cushion provided with an apron, springs for supporting the cushion, a base comprising a flat sheet metal plate substantially co-extensive with said cushion and grooved along its edge to receive the lower edge of said plate, fingers struck up from said plate adjacent said groove and bent over to clamp the apron within the groove, and means integral with the base for securing the lower ends springs thereto.

6. In a seat structure, a cushion having a depending apron, springs for supporting said cushion, and a supporting base comprising a flat sheet metal plate having an edge turned downwardly and upwardly, thereby forming an upwardly opening channel to receive said apron and forming a downwardly extending flange adapted to pest upon a support and space the base thererom.

'- 7.. In a seat structure comprising a cushion, a plurality of coil springs supporting the same and a depending apron, a

flat sheet metal base plate having fingers struck up therefrom for engaging the bottom coil of each of said springs at opposed points and having a marginal portion turned down to form a supporting and spacing flange with the edge thereof turned up forming thereby a channel to receive the lower edge of said apron, said plate having fingers struck therefrom at said'marginal portion for securing said apron in said channel.

In testimony whereof, ature. ING.
